[Openstack-operators] Shared storage HA question

Look at ceph (http://ceph.com/) for this since you are trying to use it in
cinder. We have had pretty good success with it as long as you can give
your storage network > 1gbit/s speeds.

The basic approach would be to install ceph storage nodes on your boxes
with disk in it and also install a mon process on each. Put your journals
on faster drives and install the third mon and the gateway on your
openstack management box.

There are many howtos on the ceph site for this and they are very helpful
in IRC if you have questions about it.

Hope this helps!
